the most fleeting state of arousal is

ATI RN

Human Growth and Development Final Exam

1. Which state of arousal is considered the most fleeting?

A. Regular sleep
B. REM sleep
C. Drowsiness
D. Quiet alertness

Correct answer: D

Rationale: Quiet alertness is indeed the most fleeting state of arousal. This state is characterized by a newborn infant being awake, calm, and attentive, but it is short-lived and transitions quickly to other states of arousal. Regular sleep, REM sleep, and drowsiness are not considered as brief and transitional as quiet alertness in newborn infants.

2. The more a mental ability depends on __________ intelligence, the earlier it starts to decline.

A. fluid
B. crystallized
C. emotional
D. cultural

Correct answer: A

Rationale: The correct answer is A: fluid. Fluid intelligence, which involves problem-solving and reasoning, tends to decline earlier than crystallized intelligence. Crystallized intelligence, on the other hand, involves knowledge and skills acquired over time and is more stable with age. Emotional intelligence and cultural intelligence are not directly related to the decline of mental abilities mentioned in the question, making them incorrect choices.

3. Dana is pregnant with her first child and wonders how much weight she should gain during the pregnancy. You should recommend a healthy diet that results in a weight gain of __________ pounds.

A. 10 to 15
B. 15 to 20
C. 25 to 30
D. 35 to 40

Correct answer: C

Rationale: The recommended weight gain during pregnancy depends on the pre-pregnancy weight of the mother. For a woman with a normal pre-pregnancy BMI, the recommended weight gain is typically between 25 to 30 pounds. This range is considered healthy to support the growth and development of the baby while also maintaining the mother's health. Choices A, B, and D are incorrect as they represent weight gain ranges that are either too low or too high for a woman with a normal pre-pregnancy BMI, which could pose health risks for both the mother and the baby. It is crucial to adhere to healthcare professionals' guidelines to ensure a healthy pregnancy and birth outcome.

4. Which statement is supported by research on newborn taste preferences?

A. Newborns cannot distinguish basic tastes.
B. Not until 4 months do babies prefer a salty taste to plain water.
C. Newborns prefer the taste of formula to breast milk.
D. Unlike adults, babies relax their facial muscles in response to sour tastes.

Correct answer: B

Rationale: Research on newborn taste preferences has found that not until around 4 months of age do babies start to show a preference for a salty taste over plain water. This indicates that newborns do have some ability to distinguish tastes, contrary to the statement in option A. The statement in option C that newborns prefer the taste of formula to breast milk is not supported by research on newborn taste preferences. Option D, stating that babies relax their facial muscles in response to sour tastes, is also not a supported statement regarding newborn taste preferences.

5. Tiffany is a small-for-date baby. This means she __________.

A. was born several weeks or more before her due date
B. was born below her expected weight considering the length of the pregnancy
C. will probably have much less serious problems than a preterm infant
D. may have difficulties in infancy but will outgrow them by the preschool years

Correct answer: B

Rationale: A small-for-date baby, also known as a small-for-gestational-age (SGA) baby, is a baby who is born below their expected weight considering the length of the pregnancy. This can be due to various factors including issues with growth restriction in the womb. Being small-for-date is different from being preterm (born prematurely) and does not necessarily mean that the baby was born early. Choice A is incorrect because being small-for-date does not specifically indicate being born several weeks or more before the due date. Choice C is incorrect because being small-for-date does not guarantee fewer problems than a preterm infant, as each baby's health outcomes can vary. Choice D is incorrect because while small-for-date babies may have initial difficulties, it does not guarantee that these issues will be outgrown by the preschool years.
